I NEED ADVICE💖💛

I'm a junior and I've been chatting with this boy who's in my Algebra and English class on Snapchat. One day I told my friend in my English class to follow my finsta. He must've overheard me telling her the username cuz once I got home HE requested to follow my finsta. For a week we've been snapchatting, but something changed. On Friday, everything was fine, but on Saturday, he left me on read. Today, I snapped him and he left me on read TWICE. I then went to my finsta and checked my followers. HE UNFOLLOWED!!! I'm so upset that he's been ignoring me :(. I wanna talk to him but we never talk at school, only on snap. We also are on a two week break so I cant see him. He's really attractive and I just want to get closer to him but idk what I did. Please give me advice on what to do ladies I need it💖
